Barman, Far Rochaway,N.Y., assignor to Medical Plastics, 1110., Jamaica, NY, a corporation ofNew York Filed Aug. 26, 1958, Ser. No. 757,375 5 Claims. (Cl. 128-29)The. present invention relates to a mouth-to-mouth resuscitator and itparticularly relates to a mouth-tomouth resuscitator which is made ofplastic material.

It is among the objects of the present invention to provide a novelmouth-to-mouth resuscitator which may be readily manipulated and willeliminate the necessity of physical contact between the mouth of theperson being treated and the mouth of the person seeking to accomplishthe resuscitation and which at the same time may be readily sanitized,and produced and stored under sanitary conditions.

Another object is to provide a simple, low-cost mouthto-mouthresuscitator which will be readily effective without skilled or trainedoperators and which may be readily utilized with adults, children orinfants and which will permit possible resuscitation action withassurance that the breathing operations of the respirator may beeiiectively and fully communicated to the person whose rcsuscitation isto be accomplished.

A still further object of the present invention is to provide aresuscitation apparatus in which the device will be of such low cost andof such inexpensive construction that it may be readily discarded afterusage thereof and so that a supply of such mouth-to-mouth resuscitatorsmay be kept on hand and readily assembled when needed for use withpersons of varying mouth or head sizes and with the mouth piecesbeingreadily adjustable and replaceable to lit the relative mouth sizesof the resuscitator as well as the person who is to be resuscitated.

Still further objects and advantages will appear in the more detaileddescription set forth below, it being understood, however, that thismore detailed description is given by way of illustration andexplanation only and not by way of limitation, since various changestherein may be made by those skilled in the art without departing fromthe scope and spirit of the present invention.

In accomplishing the above objectives, it hasbeen found mostsatisfactory, according to one embodiment of the present invention, toprovide an elongated, concave, deep cup member, which will closely fitthe periphery of the mouth of the resuscitating person as well as theperson being resuscitated and which will not cause any undue pressureover the area while at the same time most ettective use of the breathingapparatus of both persons involved is accomplished.

In the perfect form of the invention, the body of the cup is desirablyflexible or of a molded, flexible polyethylene plastic material with thebase of the cup and the rim of the cup being relatively rigid.

Each of the cups is desirably provided with a central nipple settingaway therefrom and these nipples may be attached to a straight, rigidtube which will constitute the connection between the cup-s in themouth-to-mouth resuscitator. v

The cups are generally of such a size that they will extend well beyondthe ends of the mouth andtend to have a resilient grip longitudinallyacross the month while theywill only contact...and "exert slightpressure along the upper and lower edges of the month where it is backedup by the upper and lower teeth.

With the foregoing and other objects in view, the invention consists ofthe novel combination, construction and arrangements of parts ashereinafter more specifically ddidfifiib i Patented Mar iz, H963described, and illustrated in the accompanying drawings, wherein isshown an embodiment of the invention, but it is to be understood thatchanges, variations and modifications can be resorted to which fallwithin the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote correspondingparts throughout the several views:

FIG. 1 is a side perspective view of the mouth-to-mouth resuscitatorshowing end cups of about the same size.

FIG. 2 is a fragmentary transverse view taken along the line 22 of FIG.1.

FIG. 3 is a transverse sectional view along the line 33 of FIG. 1.

Referring to FIGS. 1 and 3, there is shown a mouthto-mouth resuscitatorhaving the upper cup A, the lower cup B and the connecting tube C.

The upper cup A is shown as having a relatively flat base portion illwith the rather short, elongated upwardly,

curved side port-ions 11 and the deep or long end portions 12 whichterminate in the circular extension 13.

The periphery of the ends of cup A have the out-turned lips. 14 whichare relatively thick and beveled oil as indicated at 15 with theout-turned lip 14 and the enhanced thickness thereof tending tostrengthen, and giving a fairly rigid structure with the flexibilitybeing contained in the bottom wall Ill, the end walls 12 and the sidewalls 11.

It will be noted by reference to FIG. 1 that the end walls 12 and theside walls 11 are quite bulged outwardly so as to enhance theirflexibility.

The upper side edges 16 are provided with a thin, sharp lip at 17 (seeH6. 3) which will give less rigidity to the edges 16 than to the endedges or beads 14 but at the same time cause the flexibility to berestricted to the base or bottom 10, the side walls 11 and the end walls12.

Desirably the end walls 12 are thicker than the side walls 11 or thebottom wall 10 and have less flexibility so that they will clamp on tothe sides of the face beyond the ends of the mouth and tend to press theends of the mouth together to open the lips.

The central portion 18 of the base is also given rigidity by the grooveand ridges 19 which terminate in the shoulder 2t) and the nipple 21.

The nipple 21 fits into the end 22 of the tube C with the end of thetube abutting the shouder 2i Normally the nipple 21 will be taperedslightly so that there isa jamb fit in the end 22 of the tube C bythenipple 21.

When the cup A has been forced into or connected with'the end of thetube C, the nipple will be held firmly in position and the cups will beheld on to the tube C unless strong pulling pressure is applied thereto.

The structure of the edge 16 is such that it may be stretched slightlyupon forcing the side walls 12 and their end beads along the ends of themouth.

The use of a relatively flexible polyethylene for the cups A and B, anda rigid plastic for the tube C, permits the resuscitator using the cup Ato apply a flexing pressure through the cup B to the mouth of the personbeing resuscitated.

Although the cups are shown of the same size in FIG.

1, it is apparent that the lower cup may be of smaller or larger size tomatch the size of the mouth of the person being resuscitated whether itbe an infant, child or adult.

Both the cups A and B may be readily changed and substituted, dependingon the size of the mouth and face of the person involved in themouth-to-mouth resuscitation.

When applied in a mouth-to-mouth resuscitation operation, the tube Cwill carry the pressure of the normally prone person with the flexingbeing taken up by the bottom walls and primarily the side walls 11, withthe end walls 12 serving primarily for clamping purposes across the endsof the mouth.

The upper and lower cups are desirably of substantially the sameconstruction with both flexing primarily through the bottom wall 10which may be made thinner than the end walls 12 and the side walls 11,and with the beads 14 at the ends of the cup and the beads 17 at thesides of the cup giving rigidity at the line of contact at the mouth ofboth persons in the mouth-to-mouth resuscitation.

It is apparent that the applicant has provided a simple,

inexpensive, readily applied mouth-to-mouth resuscitatory device.

The cups A and B and the tube C may be readily sterilized by placingthem in hot water and different sizes may be utilized. If desired, thecups A and B may be turned at different angles better to accomplish themouthto-mouth resuscitation.

The particular mouth-to-mouth resuscitator disclosed in the presentapplication may be used by anyone whether a professionally trainedperson, a layman or by a child or adult and it is particularlyuseful incase of mass casualties and in connection with civilian defense.

It is particularly useful in that it does not require insertion of atube or a rod or passageway into the throat and since there is nolikelihood ot injury to the person whose resuscitation is necessary.

The tube C may be of cellulose acetate butyrate and it may be eight totwelve inches in length and it desirably should be rigid with onlylimited flexibility, if any.

The end cups A and B should be thinnest at their curved portions 10, 11and 12 and thickest at their rim and center portions 14, 15, 16, 17, 18and .19 with the cup portion in its intermediate areas at 10, 11 and 12being of a more flexible material or having a thickness of one-third andone-half than the rims and than the central portion 19.

The end cups A and B are relatively thin at their curved portions 11 inFIG. 3- and 12 in FIG. 2 and are thicker at their edge portions 13, 14and 15 in FIG. 2 and 17 in FIG. 3.

The intermediate cup portion-s as indicated at 10, 11 and 12 have a moreflexible material and-they should have a thickness at 10, 11 and 12which is about /:4 to /2 the thickness of the material at the rims 14and 15 of FIG. 2 and 17 of FIG. 3.

As a result the bottom and side walls 10, 11 and 12 will be relativelyflexible as compared to the rim portions 14, 15, 16 and 17 which arerelatively rigid.

The same is also true of the central portions at 18 and 19which arerelatively rigid as compared tothe flexible walls 10, 11 and 12.

The cup portions which are primarilyiforme'd'of the bottom walls 10 andthe side walls 11 and 12have a thickness of about V3 to /2 of therim'portions 14, 15, 16 and 17 and the central portions 18 and 19.

The dimensions may vary from one and one-half inches by two and one-halfinches up to one inch by'two and tone-quarter inches and generally thecup should be of such a size so as to extend beyond the ends of themonth by a dimension of oneinch to two or three inches and above andbelow the mouth so that they willpressv against the gums aboutone-quarter to one-half inches above the teeth with the total dimensionabove the mouth being about one-quarter to one and one-half inches.

The cups A and B are desirably made of a polyethylene which is rigid inthick section but flexible in thin section.

While there has been herein described a preferred form of the invention,it should be understood that the same may be altered in details and inrelative arrangement of parts within the scope of the appended claims.
